Deficits in muscular strength occur in many clinical conditions such as motor neuron disease. The inverted screen and weight lifting tests described here measure strength in mice almost exclusively, with minimal influence of factors such as coordination.

Source: Olmstead, D. N., et al., Facial Nerve Axotomy in Mice: A Model to Study Motoneuron Response to Injury. J. Vis. Exp. (2015).This video demonstrates the facial nerve crush procedure in a mouse, where blunt dissection through key landmarks exposes the facial nerve trunk at the stylomastoid foramen. Forceps are then used to compress the nerve trunk, inducing axonal damage and disrupting neuronal signal transmission.

Source: Li, Q., et al. Investigating Mammalian Axon Regeneration: In Vivo Electroporation of Adult Mouse Dorsal Root Ganglion. J. Vis. Exp. (2018)This video demonstrates the process of axonal regeneration in a mouse sciatic nerve following a crush injury. The isolated nerve is fixed and prepared for imaging, with fluorescent proteins expressed in neurons to visualize axon growth. Using an epifluorescence microscope, axon regeneration is traced from the injury site to assess the extent of...

The earliest records indicate linen was the biomaterial of choice. Catgut, which is still in use today, was reportedly used to treat gladiators around 150 AD. Today, there are numerous materials being used for sutures. Sutures are classified by their composition (natural or...

Acid Strength and Molecular Structure

Binary Acids and Bases In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...
FAQs
The measured response reflects more than particle failure alone. Under compression, particles may first rearrange within the sample or packed bed, changing how loads are transmitted; continued loading can then cause deformation or fracture. Separating these responses helps engineers determine whether a material is primarily settling into a denser structure or losing integrity through crushing.
Load-bearing capacity indicates how well a packed granular material continues to support applied force as compression increases. A decline can signal deformation, breakage, or a changing internal structure. This information is important when engineers assess whether granules or pellets can maintain their intended function during storage, transport, or operation in a packed bed.
A representative sample is essential because the measured response depends on how particles interact throughout the tested material. If the sample does not reflect the bulk solid, the observed rearrangement, deformation, or breakage may not describe actual performance. Engineering decisions based on the result could therefore misjudge handling behavior, bed stability, or product durability.
The test applies a controlled compressive force to either a representative sample or a packed bed and follows how the material responds. Relevant observations include deformation, particle breakage, rearrangement, and changes in load-bearing capacity. Together, these responses provide an engineering basis for comparing materials and identifying whether crushing may compromise later processing or use.
Engineers use the results to support material selection, process design, and quality control. The testing approach can evaluate materials intended for storage, transport, pelletizing, or packed-bed operation. By relating compressive response to expected service conditions, teams can identify materials more likely to retain integrity and make handling or processing decisions with better evidence.
Crushing can generate fines, which may alter how material flows and how resistance develops through a packed bed. It can also change the structure and performance of the product during storage or transport. Evaluating this behavior helps engineers anticipate pressure-drop changes, preserve process performance, and support safer handling of granular materials.
